Fall evenings in Oklahoma can get cold, so you need to make absolutely sure you have something to put over your shoulders to keep you warm. That's the most important part of your outdoor event wardrobe.
If the reception features a band or DJ for dancing, be sure to choose shoes you can dance in or bring a pair of slip-on flats in your clutch.
As for dress length and style, have fun! That's the point of a wedding and reception: to celebrate the couple with a party. Don't wear all white. Don't get too short or sexy. Don't get hung up on the definitions of “formal” and “cocktail attire.” Do let the event be a chance to let your personality shine through your fashion. Dance around a little bit in front of the dressing room mirror to see how you'll look on the dance floor.
If all else fails, grab your favorite LBD (little black dress) and jazz it up with a fabulous rhinestone brooch, a few stacked bracelets, chandelier earrings, a metallic or animal print clutch and a pair of modern platform pumps.
